%N Irregular table: row n (n >= 1) consists of numbers 0..A084558(n).
%C The term a(n) gives the position (zero-based, starting from the left hand end of permutation) of a corresponding permutation A055089 and A060117/A060118 from which the term A055089(n) or A060118(n) is to be picked.
%H A. Karttunen, <a href="/A220659/b220659.txt">Rows 0..720 of the irregular table, flattened.</a>
%F a(n) = n - A220657(A220658(n)).
%e Rows of this irregular table begin as:
%e 0;
%e 0, 1;
%e 0, 1, 2;
%e 0, 1, 2;
%e 0, 1, 2;
%e 0, 1, 2;
%e 0, 1, 2, 3;
%e The term 2 occurs four times in A084558, in positions 2, 3, 4 and 5. Thus rows 2, 3, 4 and 5 (zero-based) of this irregular table are all 0,1,2.
